Agent comparison

OpenAI vs DeepSeek

A controlled evaluation framework for OpenAI and DeepSeek across structured outputs, multilingual work, critical failures, and reviewer effort.

Use case: Global teams comparing hosted generalists under measurable business controls

Use case

OpenAI vs DeepSeek

Use one fixed, representative test set for global teams comparing hosted generalists under measurable business controls. Choose only after human review of accepted outputs, critical failures, and operating constraints.

Sample outputs and scoring notes

Editorially reviewed decision framework. The metric table uses the dated AAA.win preview batch; model versions are not pinned and runs have not passed the reviewed-results publication gate, so it is not a product ranking.

Latest releases

IndexNow production delivery verification

Verified production IndexNow receipt with a new key: Microsoft's external proof returned HTTP 200, single-URL GET and POST both returned HTTP 200, and eight batches covering 386 canonical URLs each returned HTTP 200 with zero retries. A second run found the inventory unchanged and sent no request.

IndexNow proof-origin protocol fix

Production Bing validation exposed HTTP 500 at the external root proof because TLS termination was followed by an internal rewrite using the wrong protocol. This release corrects that rewrite boundary, but remains unverified until the external proof returns HTTP 200, the automatic submission runs, a later canary returns HTTP 200, and the idempotent rerun passes.

IndexNow root-proof request compatibility

After v4.3.3, the exact root-level {key}.txt proof returned HTTP 200, but a full request carrying keyLocation still returned HTTP 403; a minimal homepage request with the same production key and no keyLocation returned HTTP 202. This release omits that field, while the automatic full run and idempotent rerun remain deployment checks.
